I am not a fanboy of Glock at all. When I went to get a polymer pistol I shot one and it was okay, but ended up with a Steyr M9 instead. I prefered having a pistol that had a safety option so I would not get a case of "clock leg" if something snagged the trigger when I re-holstered.
H&K did come out with the first polymer framed gun, but Glock came out with the first one that was a success. Sort of like how the Germans invented the assault rifle with the StG44 but the Russians set the tone with the AK47. Or how Henry Ford did not invent the automobile, he just made it a success.
Glock is not a walk on water pistol. I think it is probably best suited for military and law enforcement duty versus personal protection. I respect the design for its reliability and durability, but am not a fan of the ergonomics. My personal sidearms have been Steyrs, Walthers, and Berettas instead with a Ruger 357 thrown in.
If I had to pick a poly gun this size, it would be a Walther PPS
